Do you ever wish you could bring your friends to work with you? Well, this week my wish came true! Fred Armisen plays Mae’s school counselor who confronts Martin (Oliver Hudson) and Lena about their divorce being confusing for Mae (Olivia Keville) because it’s “too friendly.” He encourages us to set some new boundaries.

Plus, the actor gives us the scoop on working with guest star J.B. Smoove.

Fred and I go way back! We met while shooting the movie The Promotion in 2006 and became fast friends. When I fractured my back in four places a year later, he came over and took walks with me as part of my recovery. He was at my wedding to my husband, Lee Kirk, and later starred in a movie that Lee directed.

Oh! We even did a music video together for The Old 97s. He’s a great friend but he’s also amazingly funny and talented. When he agreed to come on the show I was SO EXCITED! It’s my personal goal to get him back for more!

Speaking of guest stars … Wes (Trent Garrett) is back! Our scene together was so heartbreaking. I have to say … I really like the energy between Wes and Lena. I kind of want them to reunite. You? I mean, Martin is happily dating Lisa Apple (Monica Barbaro). What do you think? Should Lena and Wes get back together? And, I personally love Martin and Lisa Apple.

But what I love most is Martin and Lena singing together! If you can believe it, they brought in a voice coach to help us figure out how to break down the song. I practiced forever just for that little bit of us singing. Speaking of singing … how about Olivia and her amazing singing voice! I think this may be a sign we need a musical episode. Who’s with me?!

Random fun fact: The Pomeranian that plays Camille’s pet dog on the show was also in a Rhianna video.
